Are you aware of whether any such modifications are available? I too would like to use the Ultimate GPS Logger Shield with a Due.

I tried this latest version of the Adafruit_GPS library for Arduino Due support and wired the Ultimate GPS shield to the Due as suggested and it worked just fine. Thanks to Adafruit_Support_Rick for your effort and input.
